hay guys i wrote a while back about diff problems blowing up all th e time if you dont mind a little extra weight try using the sd rear steel out drives and hardend drive shafts with acer ceramic bearings . you have too use a few mor shims but no more diff problems and no more wear when running brushless just thuoght i wiold let you all know as i was going threw so many diffs ... its certainly worth a shot and in important races it doesnt let you down
